UNITED STATES PATENT OFFICE,

TIMO. BROWN, OF GEORGETOWN, NEW YORK.

ALLO'Y COM POSITION.

Specification forming part of Letters Patent No. 16,170, dated December9, 1856.

To all whom it may concern:

Be it known that I, TIMOTHY BROWN, of Georgetown, in the county ofMadison and State of New York, have invented or discovered a new anduseful Metallic Composition or Alloy Peculiarly Suitable for MakingCheese- Hoops'; and I do hereby declare that the following is a full andexact description thereof.

Metallic cheese-hoops, if the metal were not so liable to corrosion oroxidation by contact with the acids mixed with the curd and whey, wouldin several particulars be preferable to those made of wood; but thecheap simple metals and the ordinary alloys are quickly corroded oroxidated by the lactic acid in the whey and the acid employed tocoagulate the milk, and are therefore entirely unfit for the purpose. Bymany experiments} have, however, discovered an alloy which is notaffected by the acids in the whey, continually remaining bright, howevermuch used, and in other respects possessing the proper qualities forcheese-hoops. The alloy is composed of the four metals-zinc, tin,copper, and antimony. I have found that several different proportionswill produce alloys very nearly fulfilling the required conditions; butthe best alloy which I have discovered is composed of these metals inthe following proportions, or thereabout: zinc, seventy parts; tin,eight parts; copper, one part; antimony, one part. A variation from theabove proportions I have found nearly as good as the aboveviz.,zinc,fifty-six parts; tin, eighteen parts; copper, one part; antimony, onepart., The metals are melted together in the usual manner and cast insuitable molds to form the cheesehoops.

I do not confine the alloy to any exact proportions; hut

What I claim as my invention, and desire to secure by Letters Patent, is

The metallic composition or alloy, composed of zinc, from fifty-six toseventy parts; tin, from eighteen to eight parts; copper, one part; andantimony one part, for the purpose specified.

In testimonythat the above is a true description of my improved mode ofmaking cheese-hoops I hereunto set my hand this 24th day of June, 1856.

TIMO. BROWN.
